MTB bar ends or not
If I'm not mistaken this MTB racer is using standard bar ends
in the middle of his handle bars - am I right or is this a special attachment ? Anyone ever tried it ? http://www.cyclingnews.com/mtb.php?i...hy/stage6/7890 |

Most MTB bars have thinner ends so standard bar ends won't fit in the middle of the bar. "Rik O'Shea" wrote in message om...

They were legal in racing as long as they don't protude past the normal handlebar curves. I put some on my mountain bike and with a small set of pads they are really comfortable and aero and you can really cover some distance quick. Marty |

Anyone ever tried it ? http://www.cyclingnews.com/mtb.php?i...hy/stage6/7890 Yes, I've got my own IRO Jamie Roy fixie set up with something like that, and I like it very much. I'm using some cool Thorn carbon "bar ends" in the middle, with Cane Creek stubbies on the ends. The middle "bar ends" provide a good sort of "time trial" position, very nice for fighting headwinds.

Yes, that is a problem with most newer MTB bars, due to the popular "bulge" design. Those also make it hard to mount the brake levers as far inboard as I prefer. Older MTB bars didn't have this bulge. They were 7/8" (22.2 mm) all the way along, witha shim or sleeve to fit the standard 1" (25.4 mm) stem clamp. My Iro has an older Merlin Ti bar, which uses a shim.

Instead of feeling you're crawling along that day, you marvel at the increased speed. Wind whistles past your ears. On days with a tailwind, you marvel instead at how fast you're going past rock and tree. Airspeed indicator http://www.celestaire.com/catalog/products/3806.html I don't know if it's waterproof or not. I've been assuming not on mine. It says it works by the doppler effect, which is certainly wrong, there being no doppler shift with wind. It's almost certainly measuring the wavelength change by comparing inphase and quadrature amplitudes a small distance from its ultrasonic transmitter. -- Ron Hardin On the internet, nobody knows you're a jerk. |

You're thinking of the Cinnelli mini-aerobars. They were outlawed for road racing about five minutes after they came out. I've got a set of the BBB ripoffs. Most useful. However, the set in the picture are curved like standard bar ends. -- A: Top-posters. Q: What is the most annoying thing on Usenet? |

No, the frequency is unchanged. -- Ron Hardin On the internet, nobody knows you're a jerk. |

No, the frequency is unchanged. Dear Ron, When I browsed for sonic anemometers, this sort of thing came up: "The EPA also uses sonic anemometers at some stations. Sonic anemometers operate on the principal that the speed of wind affects the time it takes for sound to travel from one point to another. If the sound is travelling in the direction of the wind then the transit time is decreased. " "Conversely, if it is travelling in the opposite direction to the wind the transit time is increased. Sonic anemometers emit sound waves, record the time taken to receive the wave at the other end of the instrument, then convert the value into the wind speed. By monitoring the speed of sound along two different axes, wind direction is also able to be measured." http://www.epa.qld.gov.au/environmen...ological_data/ I still want one for Christmas.
